The Northwest Trail Alliance builds and maintains trails in NW Oregon and SW Washington from the foothills of Mt. Hood, Mt. Adams and Mt. Saint Helens to the Pacific Coast.  These trails require thousands of volunteer hours each year to maintain to ensure continued access to high quality mountain bike opportunities in the Pacific Northwest.  Check out our trails and then come help us at our next dig day! For more information about how you can help, please contact or the leadership steward team lead for the area.
